SPECIFICATION forming part of ALetters Ibatent No. 742,486, dated October 27, 1903. Application tiled January 15, 1902. vSerial No. 89,825. (No model.)

To all whom it may con/cern:

Be it known that I, LOUIS PETER, a subject of the Emperor of Germany, and a resident of Frankfort-on-the-Main, in the German Empire, have invented a new and useful Improvement in Motor-Wheels and the Like, of

which the following is a speciication.

The object of this invention, which is applicable both to wheels with pneumatic tires and to those with solid or cushion tires of elastic material, is to afford facility for the mounting ot' the tire upon and its detachment from the rim of the wheel and to so fasten the tire to the rim that it will be secure against creeping or other displacement; and to these ends the improvement consists in the novel construction and combination of the rim and tire hereinafter described and claimed.

Figure 1 is a side View of a wheel-rim constructed according to my invention; Fig. 2, a transverse section of the rim with the tire mounted and secured thereon; Fig. 3, a view corresponding with Fig. 2, but with the two members of which the rim is composed separated from each other.

A designates the tire, of elastic material,

' having a cylindrical inner surface or base and having flanges j, one on each side, projecting outwardly and laterally from its base.

ct c bb designate the rim, composed of two separable members a c and b b'. The mem,

ber a c comprises an externally-cylindrical portion a, which receives the base of the tire, and an inwardly-turned iiange c, which overlaps one of the external Iianges j fot' the tire. The member b b consists of a ring b, a portion of which is cylindrical internally and encircles the cylindrical part a of the rim at one side of the tire. The said member b b has a iiange b overlapping the other external flange j of the tire, and it has also an internal :liange or rib g, which enters a corresponding recess or groove h in the part a outsideof the flange j on its side of the tire. To provide for the placing of the said member b b over the edge of the part aand over the tire-flange, it is divided, as shown at d in Fig. 1, and provided with lugs f, which are tapped to receive a right and left hand threaded screw e, by the turning of which in one direction the said member is contracted to clamp it upon the tire-ange and clamp the tire to the part a. By turning the screw in the opposite direction the said member may be expanded sufticiently to permit its removal sidewise from the member a c and the tire and permit the removal of the latter for renewal or repair.

In Fig. 2 the base of the tire and its flanges also are represented as having an internal stiening c', by which they are prevented from stretching and made to give the tire a rigid foot. This stitfening may be a hard rope of suitable fibrous material.

What I claim as my invent-ion is` 1. In wheels for motor-vehicles and the like, the combination of a tire the foot of which is stiened and has a cylindrical inner surface, a rim member consisting of a fixed cylindrical part tting tightly within the/whole width otv said cylindrical surface and provided on one side of the tire with a fixed inwardly-bent flange, a removable rim member applied on said fixed member at the other side of the tire and provided with an inwardly-bent flange, and means for clamping said removable member upon the first-mentioned member and upon the tire.

2. In wheels for motor-vehicles and the like, the combination of a tire the foot of which is stiffened and has laterally and outwardly projecting stiened iianges and a cylindrical inner surface,a rim member consisting ofa fixed cylindrical part fitting tightly into the cylindrical surface of said tire and provided with a fixed inwardly-bent flange, a removable rim member provided with a cylindrical inner surface and with an inwardly-bent ange, and means for fixing said removable member on the first-mentioned member.

3. In wheels for motor-vehicles and the like, the combination of a tire having a cylindrical inner surface and lateral stittened anges, a rim member consisting of a tixed cylindrical part tting tightly into the cylindrical surface of the tire and provided with a xed inwardly-bent; flange and with a recess in its In testimony whereof I have signed my own cylindrical surface, a slib removable part name to this specification in the presence of provided with a cylindrical inner surface and two subscribing Witnesses.

an inwardly-bent flange and with a rib tting LOUIS PETER. into said recess, and means for clamping said Witnesses: removable member over lhe first-mentioned JEAN GRUND,

member. CARL GRUND.
